Ballycastle Wind Statistieken, July gemiddelde vanaf 2006

The figure shows how often and how strongly the wind blows from different directions over a normal July. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 1984 NWW3 forecasts of wind since since 2008, at 3hr intervals, for the closest NWW3 model node to Ballycastle, located 36 km away (22 miles). There are too few recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3.

According to the model, the most common wind at Ballycastle blows from the WNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Ballycastle. Converseley, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical July, the model suggests that winds are light enough for the sea to be glassy (light blue) about 10% of the time (3 days each July) and blows offshore 28% of the time (0 days in an average July). Over an average July wind stronger than >40kph (25mph) was expected for only a single days at Ballycastle

IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
